    What would the compression ratio be with 98cc cylinder heads ?

    Asked by: The gas man
    Thank you for your inquiry. Going off a 1973 Chevy 454 engine using the Sealed Power H661CP100 Piston sitting .038" below deck, a head gasket with a 4.580" bore .039" compressed thickness your compression ratio would be around 9.13:1
